SPECIFICATION forming partof Letters Patent No. 610,941, dated September20, 1898.

Application filedA July 30, 1897.

To all whom t may concern:

Be it known that I, JOHN ERBEN, a citizen of the United States, residingat Cleveland, in the county of Cuyahoga and State of Ohio,

have invented certain new and useful Improvements in Stoves or Ranges;and I do declare the following to be a full, clear, and exactdescription of the invention, suoli as will enable others skilled in theart to which io it appertains to make and use the same.

My invention relates to stoves and ranges and seeks to improve that typeof stove and range which comprises a casing, an oven disposed above thebottom wall of the casing so as to form a lower horizontal flue andhaving its side walls arranged at a distance from the side walls of theeasing so as to form vertical flues in communication with the lowerhorizontal flue, an ash-box of less width than the 2o oven arrangedabove the middle of the same, a fire-box arranged above andcorresponding in width at its bottom to the ash-box and havingoutwardly-flared side walls serving in conjunction with the top of thecasing to form z 5 horizontal iues,and an upright iiue connected withthe lower horizontal iiue.

The invention will be fully understood from the following descriptionand claim when taken in conjunction with the annexed draw- Figure l is avertical transverse section of a stove or range embodying my invention,and Fig. 2 is a vertical longitudinal section taken in the planeindicated by the line a: m

of Fig. I.

Referring by letter to the said drawings, A indicates the casing of myimproved stove or range, which is preferably constructed of steel plateand is of the ordinary rectangular 4o form. This casingAhas a pluralityof holes a in its top wall b, which are normally closed by removablelids c, and it is also provided on said top Wall b with a collar-flanged, which surrounds an opening CZ' and is designed for the ordinaryconnection of a smoke-pipe e, as

shown in Fig. l of the drawings.

B indicates an upright flue which is ar ranged at the back of the stoveor range in communication with the opening d in the top 5o and has theopeningg below the top for a purpose presently described, and Cindicates Serial No. 646,541. (NO model.)

an oven, both flue and oven being preferably constructed of steelplates. The said oven C extends from the flue B to the front of thecasing, where it is provided with a door D, and it is disposed about theproportional distance illustrated from the end Walls h of the casin g Ato afford flues E and is also disposed about the distance shown abovethe bottom wallfof the casing to form a Hue F, which is 6o in constantcommunication with the fines E, as shown, and is preferably providedwith a cleaning-door G. The iiues F and B are connected by an openingc', (see Fig. 2,) and in order to prevent a too direct passage of smokeand products of combustion from the flues E to the flue B thevertically-disposed bafflestrips II are provided in the ue F, as shown.These strips Il extend from the rear wall L of the line F to a pointadjacent to the front 7o Wall of the casing A, and, being disposed oneither side of the opening t', they serve to cause the smoke and otherproducts of combustion to pass in close proximity to all parts of thebottom wall of the oven, so as to insure an even heating of said wallthroughout its area. The said strips Il are connected to the casing-Wallf and the bottom wall of the oven by bolts j, and they are consequentlyenabled to serve the additional function of supports 8o for the oven, aswill be readily appreciated.

Above the oven C is disposed an ash-box I, which has a door J for theconvenient introduction and removal of an ash-pan K. This ash-box Iextends from the flue B or from the inner rear wall L of the stove tothe front wall thereof; but it is considerably less in width than theoven C and is disposed above the middle of the same, as best shown inFig. 2, so as to expose a considerable portion of the 9o area of the topwall 7.; of the oven to the direct contact of the products ofcombustion, as will be presently pointed out.

Above the ash-box I is disposed the firebox M, which extends from theWall L to the front wall of the casing A and has a suitable grate N inits bottom, as shown. At its bottom this lire-box M corresponds in widthto the ash-box I; but from such point its side walls P are dared so asto increase its carco pacity and afford a larger surface of fire, whichis desirable in order to evenly heat the top wall b ot the casing. Thesaid walls P merge at their upper edges into horizontal Walls Q, andthese walls Q, which serve in conjunction with the top casing-Wall b toforni a iiue or iiues R, merge, in turn, into depending Walls or skirtsS, which form the vertical flues E in alinement with the tlues E, andserve to preventa direct passage of the flame and products of combustionto the top Wall of the oven C, and thereby obviate a too high heating ofsaid Wall, Which would result in scorching the top of the substancebeing baked. This is an important feature of my invention, because iteffeetually prevents scorching of the top of the article being bakedbefore the other parts of the same are cooked, which is adesideratum.The depending walls or skirts S also tend to prevent the deposit of sootand other products of combustion on the top wall C, and consequently thesaid Wall will be sufficienti y heated, notwithstanding the fact thatthere is no direct passage of the flame and products of combustion tothe same.

T indicates a damper for controlling the opening g. This damper T isshown as fixed to and movable With a rock-shaft having a crank at oneend; but it is obvious that it might be opened and closed in anysuitable manner and through the medium of any preferred device. Saiddamper T is designed to be opened When a iire is Iirst started to permitof a direct passage of the smoke and other products of combustion to thesmoke-pipe e; but when the iire is Well started it is closed, so as tocompel the smoke, dames, and other products of combustion to take thecourse indicated by arrows. This course is from the re-boX through theiues R, the iiues E; the flue F, the opening t', and the flue B to thesmoke-pipe E. In consequence of such passage of the flame and otherproducts of combustion it will be observed that the top, side, andbottom Walls of the oven will be subjected to a uniform degree of heat,which will preclude the possibility of any part of an article in theoven being baked faster than the remainder thereof.

It Will be observed that by reason of the construction of the tire-box Mand the arrangement ot the same adjacent to the top Wall of the casingthe said top Wall will be highly and uniformly heated throughout itsarea, so as to quickly cook any substance that may be placed in cookingutensils thereon. Again it Will be noticed that the arrangement of partsdescribed permits of the oven being made very large Without thenecessity of the casing being any larger than thecasing of an ordinarysteel-plate range, Which is an important advantage and a desideratum instoves and `ran ges.

Having thus described my invention, what I claim is- The stove or rangedescribed comprising essentially a casing, the oven disposed above thebottom wall ot the casing so as to form a low horizontal flue and havingits side Walls arranged at a distance from the side Walls of the casingso as to form vertical lues E communicating with the lower horizontalflue, the upright flue D connected With the low horizontal flue, theash-box of less width than the oven arranged above the middle of thesame, the fire-box arranged above and corresponding in width at itsbottom, the horizontal Walls Q forming continuations of the side wallsof the fire-box and serving in conjunction with the top of the casin gto form upper horizontal flues R, and the skirts S depending from theouter edges of the Walls Q; the said skirts serving in conjunction withthe side walls of the casing to form vertical fiues E disposed in aplane above the oven and coincident with the liues E, whereby the iameand products of combustion are conducted down to the lower horizontaliiue and a direct passage of flame and products of combustion to the topWall of the oven and the deposit of soot and ashes thereon is prevented,as and for the purpose specified.

In testimony whereof I afiix my signature in presence of two witnesses.

JOHN ERBEN.
